I

. A member u has ho n n. .F a 2- the awings i pr d a either ndf f the bed of the machine and is located in such a position that it will form a notch in the sheet of metal at the proper point- 7 As both of these notchers are identical in their construction and operation it is only thought necessary to describe the construction and operation of one of the devices. A bracket 65 is provided upon the outsidev of either of the side frames and supports the outer end of the notcher shaft 66, the inner. end of 75 said notcher shaft having a bearing within. the notcher bearing 67 "whieh is secured to the side frame provid d with an outo ward eXteiiSioI1 ,l0cated within an aperture 68 within the side Tihe hait 6B is provided with a shoulder'fihand the loose clutch member '70 is loosely illollht'ed upon the reduced portion of the shaft and i'sheld betwe n the shoulder and the bracket '65, said l'oose clutch iieinber eing provided with a sprocket 7 1. 7 Thefixejd clutch mem- I ber 72fis slidably' mounted for lateral movement upon the' hait 66 by means 0f the feather 73 and is pl-ended with a t ethY t,

The cam and pitman wheel 25 is provided with a lug 86 having the wedge shaped forward extension 87 adapted to engage the lower extremity of the lever 88 which is pivoted at 89 to a bracket 90 secured to the side frame 2. The upper end of the lever 88 is provided witha pin 91 which engages the annular groove 76 in the clutch member 72. A spring 92 bearing against the lower end of the lever 88 is adapted to; normally hold the clutch member 72 out of'contact with the member 70.

A lever 93 is pivoted at 94 to a bracket 95 carried by the side frame 1, and said leveris provided at its upper end with a pin 96 located within the annular groove 76 of the clutch member 72 of the right hand notcher. A link 97 connects the lower end of the lever 93 to a bell crank 98 which is pivoted at 99 to a bracket 100 carried upon the inner face of the side frame 1, said bell crank lever being connected by a link 101 to the treadle 102. ,A spring 103 is interposed between thelower end of the lever 93 and the side frame 1, adapted to normally hold the clutch member 72 out of engagement with the clutch member 70.

The sliding clutch member 12 upon the sliding shaft 9 is provided with a lug 104, which normally lies within the notch 105 located within the boss 106 which is provided upon the inner face of the side frame 1 but when the sliding clutch member 12 is moved into contact with the clutch member 11 upon the gear wheel 8 the lug 104 is brought out of the notch 105 and as the clutch member 12 rotates thev lug rides around the face 107 of the boss 106 until it has made one complete revolution when by means of the spring 23 acting upon the bell crank lever 13 the clutch member 12 will be thrown out of engagement with the member 11 upon the gear wheel the lug 104 being reseated within the notch 105 thereby bringing the shaft 9 to a stop.

In operating the machine, a sheet of metal designated by the letter A is placed upon the bed of the machine and against the back gages 108 as shown in Fig. 6 of the drawings: The treadle 19 is then depressed operating the bell crank lever 13, through the medium of the link 18, the pin 14 upon the bell crank lever carrying the slidable clutch member 12 into connection with the clutch member 11 upon the gear'wheel 8. As the gear wheel 8 is being constantly rotated by the pinion 7 the clutch member 12 will be caused to rotate and as said clutch member is mounted against rotation upon the shaft 9, the shaft will be caused to rotate. also. As soon as the clutch member 12 starts to rotate thelug 104 will be moved out upon the face 107 of the boss 106 out of alinement with the recess 105 and the clutch member .12 andshaft 9 will be allowed to make one complete revolution at the end of which the spring 23 acting upon the extension 22 of the bell crank 13 will throw the clutch member 12out of contact with the member 11., the lug 104 being reseated withinthe recess 105 :thus bringing the shaft to a stop. lVhen the shaft 9 starts to rotate the beveled face 87 of the lug 86 which is mounted upon the cam and pitman wheel 25 will contact with the lower extremity of the lever 88 throwing the clutch member 72 into engagement with the clutch member thus causing the notcher at the left side of the machine to operate" The clutch upon this notcher operates the same as the clutch upon the shaft 9 and-comes to a stop after one complete operation of the notcher has been made. In Fig. 7 of the drawings is shown the position of the several parts of the machine as the notcher die is moved down through the sheet of metal.

While the notcher is being operated as described the pitmen rods upon the cam and pitmen wheels 24 and 25 will raise the hammer-into the position shown in Fig. 7 p and the links operated by the cam tracks upon said wheels will lower the form into the position shown, and the eccentric 56 upon the shaft 9 will cause the folder blade to move up toward the sheet of metal and as the operation iscontinued said folder blade will be moved into the position shown in Fig. 8 folding the sheet of metal into the form as shown. A further operation of the eccentric moves the folder blade out of contact with the sheet and the links operated by the cam tracks upon thewheels 24 and 25 will raise the form shown in Figs. 4 and 9, while the pitmen rods will bring the hammer down upon the sheet of metal in the manner shown in this figure. This entire operation takes place during one complete revolution of the shaft 9 and as the revolution of the shaft is completed the clutch member 12 will be brought into its initial position the lug 104 thereon registering with the recess 105 in the boss 106 bringing the shaft to a stop. here it is desired to form a notch upon the right side of the sheet the independent notcher upon the right side of the machine is operated by means of the treadle 102, the sheet being placed in the right side of the machine and in contact with the right side gage 1.09 instead of being held against the left side gage 110 as is done when the left hand notcher is used. After the notch has been cut the treadle 19 must then be depressed in order to throw the shaft 9 into operation to complete the bending of the sheet. 1

The product of this machineis shown in Figs. 19 and 20 of the drawings. The nose B is formed by the notcher and the foldedover portion O which forms the slip joint is shown more clear in Fig. as extended beyond the fold D. .It should be noticed that at D and E a slight spring is formed in the metal due to the hammer being of less width than the fold which is madeby the ,folder blade as best illustrated in Fig. 9 of the drawings. The article shown in {Figs 1 9 and 20 is designed to be afterward formed into a gutter F as shown. in Fig. 21, the, side adjacent the nose B being formed into a roll G. The slip joint formed by this machine is adapted to receive the plain end of an adjoining sectionof glittering, the forwardly projecting lip H and the nose B upon the roll G serving to guide the adjoining 'section of spouting. 'By means of the spring imparted to the joint from the folds at D and E the end of the adjoining section is thus held firmly in place within the slip joint.

Although the drawings and above specification disclose the best mode in which I have contemplated embodying my invention Idesire to be not limited to the details of such disclosure, for, in the further practical application of my invention, many changes in form and construction may be made, as circumstances require or experience suggests, without departing from the spirit of the invention, within the scope of the appendedclaims,
